DESCRIPTION
The ST20-PPI parallel port to OS-Link interface is
a host interface to allow connection from a PC par-
allel port to any OS-Link based ST20 development
board such as the ST20450-SAB. The interface
plugs into any standard PC 25 way D-type parallel
port. Supported parallel port modes are:
• Nibble mode
• Byte mode
• EPP mode
depending on which mode the host PC can sup-
port. Connection to the development target is via a
differential OS-Link connector, as used on the IMS
B300 and ST20450-Development Board. Once
connected, the development target can be ac-
cessed with the standard ST20 Toolset using the
MS Windows drivers supplied.
